 Description
. Mode of Operation
The inverter converts the DC voltage generated by the PV modules into AC voltage and feeds it into the grid.
Thefeed-in process begins when there is sucient sunlight and a specic minimum voltage is present in
theinverter. If, as it gets dark, the voltage drops below the minimum voltage value, the feed-in operation ends and
the inverter switches o.

transistor output. It is designed according to DIN EN -:- (pulse output devices for electromechanical
and electronic meters).
NOTE
The S interface sends a specic number of pulses per kilowatt-hour output. The adjustable pulse
rate
The number of pulses per kilowatt-hour output that can be sent by the S interface depends on
themaximum feed-in power of the inverter and can be set in the menu.
30.0-36.0 TL3 500, 1,000 or 2,000 pulses/kWh.
39.0-60.0 TL3 500 or 1000 pulses/kWh
72.0 TL3 500 pulses/kWh
... Digital input "inverter o"
If Powador protect is installed as a central grid and system protection, the fail-safe disconnection of suitable
Powador inverters from the public grid can be initiated by a digital signal instead of tie circuit-breakers. This requires
the inverters in the photovoltaic system to be connected to the Powador protect. For information on the installation
and use see this manual, the Powador protect manual and the instructions for use of the Powador protect on
theKACO web site.

NOTE
When the line resistance is high (i.e. long grid-side cables), the voltage at the grid terminals of
theinverter will increase during feed-in to the grid. The inverter monitors this voltage. If it exceeds
the country-specic grid overvoltage limit value, the inverter switches o.
